Join Exploratorium senior scientist Paul Doherty once more as he serves up hands-on activities related to Antarctic science. Join Exploratorium senior scientist Paul Doherty as he serves up more hands-on activities related to science in Antarctica. Join us in conversation with David Ainley and other researchers, as they wrap up there field season at the Adelie penguin breeding colonies in Antarctica’s Ross Sea. Penn State University glaciologist Dr. Richard Alley explains why ice is cool. Today we wrap up our conversations with the ANDRILL scientists (including project leader Dave Harwood) and hear about what lies ahead for the project. Join Exploratorium senior scientist Paul Doherty as he serves up hands-on activities related to science in Antarctica. What have scientists learned from the South Pole Telescope so far, and what work needs to be done this year as the scientists fine-tune this amazing new piece of technology? What is dark energy? Cosmologist Rocky Kolb explains how the South Pole Telescope will help us understand the properties and nature of this mysterious force. Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms). How do ANDRILL scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it?
